Patent JP-H0418727-A (JP)
Title: Vertical diffusion device
Inventor: KOBAYASHI HIDEO
IPC: H01L21/31
Filed: 1990-05-11
Abstract: PURPOSE:To enable H2 gas and O2 gas to be ignited using the heat generated by a heater 1 thereby making the combustion in a combustion part feasible by providing the combustion part in the thermal insulator filled up part in a cap. CONSTITUTION:Since a combustion part 5 is provided in the thermal insulator filled up part 7 in a cap 3, H2 gas led-in from an H2 gas nozzle 8 and O2 gas led-in from an O2 gas nozzle 9 are ignited by the cap 3 heated with a heater 1 so as to combust in the conbustion part 5. Resultantly, since the thermally equalized region by the heat generating part 1a of the heater 1 will not be shortened while the heat generated by the heater 1 is used during the ignition time, the sequence of ignition and extinction is simplified. Besides, the title device can be miniaturized and simplified while eliminating the fitting part in low reliability so that the unfavorable effect of external leakage of the pollutant and inner gas due to the leakage of open air from outside to inside of the combustion part 5 may be averted. Furthermore, the gas leading-in step can be facilitated by leading-in the gasses after the combustion of H2 gas and O2 gas using a gas leading-in and exhausting pipe 14 also the temperature stability of the wafers 6 loaded on a wafer boat 4 (quartz-made) can be enhanced by supplementing the heat dissipation from the lower part of the heater 1 with the combustion heat of H2 gas and O2 gas.

Title: Timer circuit
Inventor: MAKINO TETSUO
IPC: H03K17/28
Filed: 1981-08-06
Abstract: PURPOSE:To supply an accurate timer signal by adding or deleting a timer signal when the vaue of a counter which counts the timer signal coincides with the output of a switch stored with a previously calculated correction value. CONSTITUTION:An oscillating circuit 1 supplies a clock signal 4 to a CPU3 and a frequency dividing circuit 2. The circuit 2 processes the signal 4 by frequency division to output a timer signal 5. When the period of the signal 5 is, for example, 0.998ms for the 1,000Hz ideal frequency of the signal 5, a correction value 500 is set previously in a switch 8. When a counter 7 counts the signal 5 up to 500, a comparing circuit 9 outputs a strobe signal 10 for coincidence to switch a changeover switch 11 to a gate 12, and while the signal 5 is thinned out before being counted up to 500 and supplied to the CPU13, the counter 7 is reset. When the period of the signal 5 is, for example, 1.002ms, on the other hand, the switch 11 is changed over to the side of a one-shot circuit 13 before the signal 5 is counted up to 500 and one pulse obtained differentiating the leading edge of the output of a circuit 13 through a differentiating circuit 14 is added to supply the resulting signal to the CPU13.

Filed: 1989-05-16
Abstract: PURPOSE: To ensure complete operation under overload by providing a signal delay selecting/comparing section and a section for controlling driving of one or more load thereby realizing an appropriate delay operation around selected one of two loads.

Title: Recorder
Inventor: ASANO SHINYA
IPC: B41J13/076
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce weight of a driven roller by forming the driven roller of aluminum, and applying allogine treatment on the driven roller. SOLUTION: A pinch roller 7 is formed of aluminum, and allogine treatment is applied to both the outer peripheral part and the shaft part. An outside diameter D1 of the pinch roller 7 is set almost equal to or slightly smaller than an outside diameter D2 of a sheet feeding roller 6. Corrosion by an ink mist contained in a machine inside atmosphere delivered by a recording head cartridge and abrasion when sliding for many hours between it and a pinch roller holder, can be reduced by applying the allogine treatment, so that a rotary load of the pinch roller 7 hardly increases even after long-term use.  Since the outside diameter D1 of the pinch roller 7 and the outside diameter D2 of the sheet feeding roller 6 are almost the same, when supplying a sheet, the sheet can be easily introduced to a contact point of the pinch roller 7 and the paper feeding roller 6 to reduce push-in force of the sheet.

Filed: 1977-10-13
Abstract: PURPOSE:To lap concave spherical surfaces with high precision, by rotating and revolving rollers in conical roller bearing, and by enlarging the swinging angle of a lapping rod fixed on one roller. CONSTITUTION:When inner track ring 10 of a conical roller bearing is rotated by motor 15 via driving member 11, roller 8 rotates and revolves between inner and outer track rings 5 and 10. Lapping rod 9 fastened to roller 8 makes the same movement. On the other hand, a work having a concave spherical surface is fixed to work holder 2.

Title: Production of aluminum nitride powder
Inventor: HATANO SHOGO
IPC: C01B21/072
Filed: 1985-06-07
Abstract: PURPOSE:To obtain the AlN powder which is fine and has few flocculated material by specifying a raw material in the titld method wherein Al2O3 and Al(OH)3 are used as the raw material and both these and a carbonaceous substance are calcined in the nonoxidizing atmosphere contg. N2. CONSTITUTION:Aluminum ammonium carbonate hydroxide (AACH) of Al compd. shown in a formula, a carbonaceous substance and/or a substance producing the carbonaceous substance at the temp. below the calcining temp. are calcined in the nonoxidizing atmosphere contg. N2. Thereby AlN powder which has normally about <=0.5mu mean grain size and is fine and few in a flocculated material is obtained. By this method, since the fine grinding of hard Al2O3 is not necessitated like a case wherein Al2O3 is used as the starting raw material, the decrease of energy cost and the mixing of the impurities are prevented. Also the calcination temp. is low and the high degree of nitrogenation is obtained and the high-purity AlN powder is obtained because AACH is easy to highly purify.

Filed: 1992-05-15
Abstract: PURPOSE: To make it possible to obtain a high-quality image by previously and exactly predicting the quality of the image obtd. by a lithographic printing in color trial printing before the execution of the lithographic printing. CONSTITUTION: A transparent cover sheet and a photosensitive compsn. layer are laminated in such a manner that a highly adhesive surface comes between the transparent cover sheet and the photosensitive compsn. layer. The photosensitive compsn. layer formed in such a manner is projected and exposed with chemical rays over the entire part thereof via the transparent cover sheet. The exposure is executed without using a photomask. If a laser beam is otherwise used for the exposure, the entire part of the photosensitive layer is exposed as there are no image and non-image on/off signals. The transparent base is thereafter continuously peeled from a receptor base at a specified speed at the room temp. and the photosensitive layer is developed by a dry process.  The parts exposed imagewise in the initial exposure stage remain on the adhesive layer of the receptor base and the unexposed parts remain on the highly adhesive surface of the transparent cover sheet.

Filed: 1983-07-07
Abstract: PURPOSE:To secure the shared use of a time base among plural servo circuits by detecting the time with a time base independent of the servo circuit. CONSTITUTION:When an interruption control signal is supplied at a CPU14, the count value of a latch circuit 11 is fetched and stored to an RAM16. At the same time, the time point where the preceding pulse signal is generated is read out and the cycle of the pulse signal is obtained. Then an error to a target cycle is detected from the target cycle stored in an ROM15, and this detected value is multiplied by the speed gain and stored to the RAM16. In the same way, an error to a target phase stored in the ROM15 is detected from the phase difference of the servo pulse signal and multiplied by the phase gain to be stored to the RAM16. These two values stored in the RAM16 are added together and delivered in response to the control range of a PWM converting circuit 19. Then the servo control is carried out with the phase and the speed of a motor 21. In the same way, the speed servo control is also given to a capstan motor 22.
